2015 Volkswagen UP 1.0L Petrol · VE65 BDU

The vehicle is currently roadworthy, but the maintenance history reveals a recurring issue with engine emissions performance. While it passed the most recent test in September 2025 at 43,838 miles, this followed a failure just eleven days prior due to high carbon monoxide and erratic lambda readings. The recurrence of these exhaust faults in both 2024 and 2025 suggests a persistent fuel-mixture issue or sensor fault that required intervention shortly before the final successful retest. At 43,838 miles, this 11-year-old Volkswagen shows significantly low mileage, averaging approximately 4,000 miles per year. The usage pattern appears very infrequent, with only 1,000 miles covered between October 2023 and September 2024, and another 1,400 miles between September 2024 and September 2025. Such low usage often results in less mechanical wear on drivetrain components, but it can also lead to degradation of rubber seals and carbon buildup if the vehicle sits for long periods. A buyer should prioritize inspecting the exhaust management system to ensure the previous emissions failures were properly rectified rather than masked. The repeated lambda sensor and carbon monoxide failures indicate a potential faulty oxygen sensor or catalytic converter that may affect fuel economy. Given the low mileage, a physical inspection should also check for brake corrosion on the metal discs and perished rubber suspension bushes, as these components often age faster than they wear on vehicles that are rarely driven.
